Abstract

Physiological and behavioural characteristics reflect carabid beetle specific requirements for habitat. There is a strong correlation between body shape and habits in species with different lifestyle. In this study, I compare the morphometry and characteristics of compound eyes in two European congeners: Harpalus rufipalpis and H. distinguendus. Both are zoospermophagous species inhabiting open habitats.

Keywords: morphometry, beetle compound eye, carabid beetles, Harpalinae, zoospermophagous
